T0 LZZ whom t may concern:

Be it known that I, Janus A. GHARNLEY, of Providence, in lthe State of Rhode Island, have invented a new and useful Machine for Engraving Vire; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof. Y

Figure l is a side elevation. Fig. 2 is atop view. Fig. 3 is an end elevation. Fig. 4 is a top plan View of my machine, with the beam d, guide d', and brace d2 removed. Fig. 5 is a perspective view of beam d, guide d', and brace d2.

My machine is designed for the engraving of wire to be used in the ornamentation of jewelry and other articles; and it consists in the construction, combination, and operation of a pair of engraving-rollers, pinions, endless" screw, blocks, set-screws, and guides, as hereinafter described. y

'Ihe engraving or impressing of any ornamental figure or pattern upon small wire which vis itself to be used in the ornamentation of other articles, if done by hand, would require an amount of time and labor that would render its manufacture utterly mpraoticable.

The object of my invention is to overcome this difficulty and to manufacture ornamental wire with such rapidity, and consequently so cheap, that it will be available for the ornamentation of a great variety of articles.

In the drawings, a is the frame of the machine, which is secured to a suitable bed. Vithin the frame a are two rolls, c c', which have engraved upon their exterior surfaces the ligure or pattern which it is desired to place upon the wire. The journals of the rolls c c extend beyond the frame c at one end,A and are provided with pinions b b. v stationary, while the roll c is adjustable through the sliding blocks w z, in which it finds a bearing, and the set-screws ff.

h is an endless screw working in the pinions b b, and t0 which motion is imparted through the band-wheel e. There are two guides, d', one attached to the lower side of the frame a, and the other on the upper side,which extend, one upward and the other downward between the wire is delivered. bearing, and the axis of this roll is at right an- The roll c' is -the action of the engraved surfaces.

the rolls c c until their thinner ends nearly meet, `which hold the wire g in place between and at the bite of the rolls c c. areV V-shaped, or made thin at one of their ends, so that they may extend up and down between the rolls e c. The thicker ends are provided with two slots, d3, running lengthwise the guide, by means of which, together with brace cl2 and screws, they are secured to beam d. Then' beam d is secured to frame a by means of screws. The slots cl3 in the guides d are for the purpose of allowing the guides to be adjusted to different size wires.

g is a piece of wire passing through the rolls c c. This wire is conducted to and from the machine by pipes or tubes attached to the machine in a proper position. 'Ihe rolls c c slightly converge toward that end from which The roll c has a xed gles to the frame a; but the roll c has adjustable sliding blocks w z, and the axis of roll c is set farther from the laxis of roll c at one end than at the other end. The surfaces of the rolls are therefore closer together at one end than at the other. The roll c is adjusted by set-screws f f, which turn in screw-bearings in one end of frame a, and are properly sc cured to blocks w z,- or I may make the rolls smaller at the unengrav'ed ends` than at the engraved ends, which would answer the same purpose as canting the roll c.

Ihe operation of my invention is as followst Motion is imparted to the endless screw h by the band-wheel e, which communicates motion to the rolls c c through the pinions b b. The wire g is now introduced between the rolls c c between the guides d. The rolls c c both ,rotate in the same direction, so that while the tendency of one is to carry the wire downward the tendency of the other is to carry it upward, the result of which is, that it is retained in its place while it is turned by and submitted to The rolls c c', converging slightly, as descrbed,together with the action ofthe engraved surfaces, draw the wire through without the assistance of other feeding mechanism, as the pattern to be wrought on the wire is engraved upon the Surface of the rolls on a spiral line.

These guides The space between the rolls e c may be regulated to the different sizes of wire by the setserews ff.

That I elaiin as my invention7 and desire 5 to see-nre by Letters Patent7 is- A machine for engraving Wire, consisting 0f frame a, endless screw h, roll c, supported in fixed bearings7 roll c, eanted and supported in adjustable bearings fw z, both having on 1o their surfaces an engraved pattern passing spirally around said rolls, beams d, braces (l2, and guides d', having slots d, adapted to hold the wire in place, and capable of being adjusted to hold different size wires, all arranged substantially as described7 and for the purposes 1 5 Set forth.
